Abstract :
The paper presents analysis of simultaneous use of multiple description coding (MDC) algorithm and multipath routing for IP-based videoconferencing system. Experimental results are given for time division of video stream in two and three substreams, compressed by H.264 codec with different quality factors (Q) and different packet loss rates in network (from 0% to 50%). Video quality is estimated with the use of two reference quality criterions: Peak Signal-to-Noise Ratio (PSNR) and Video Quality Metric (VQM).
